Almost all other database systems are based on a disk-centric model, hundreds of times slower than a RAM-centric model. WebDNA writes individual changes to the RAM image of the data and a separate process maintains a current copy of the RAM data on the disk, within your site hierarchy. You can directly backup, upload or download your database content anytime, using ftp, and manipulate it using Excel or equivalent. You can also encrypt it if some data is sensitive.

Further, you are not limited by the number of databases you can create, nor by their size.Christophe Billiottet
